I do on occassion utilize a reinforced instructors belt in a similar fashion. I made my keepers out of thin strips of velcro - they match the belt perfectly. This also locks my holster in position.
This rig does have a professional look to it, but does not convey the LE wannabe look. If I wanted to get that look, I would hook up my old basket weave rig and drop my beloved Mod. 66-2 in it. Still have the speed loader and cuff cases. No law against it but just not my style..............normally, hmmm maybe one Sat. for breakfast and observe whether the looks are any different.
